Which document is essential to initiate a claims process?

The proof of loss statement is a fundamental component in initiating a claims process because it formally documents the insured's assertion of the loss and serves as a basis for the insurance company to evaluate the claim. This document typically requires the policyholder to provide detailed information about the incident, the nature of the loss, and the amount being claimed. By submitting this statement, the insured allows the insurer to assess the validity of the claim and determine the appropriate compensation according to the terms of the policy.

While other documents, such as a claim report or the original insurance policy document, may play important roles in the claims process, they do not serve the specific function of formally initiating the claim. The claim denial letter is also not relevant at this stage, as it represents a response to a previously submitted claim rather than a document required to kickstart the claims process.
